here is a message posted by Joep Stevens from SANPARKS earlier this year.
Yes, indeed, the first Wild Cards have been sent out but there are many that still have to receive theirs. Until you have received your (new) Wild Card, you can use Wild Card number if purchased from SANParks (not Infinity) after 12 November 2010 and for old Infinity Wild Card members present this old Infinity Wild Card with letter of confirmation with the normal means of identification when visiting relevant parks, should membership still be valid, of course. The most important matter is that we have your complete and updated personal and contact information (which in many cases is still lacking, thus the slow issuing of Wild Cards). If you wish to confirm that we have all your details, you are welcome to send me your Wild Card number to firstname.lastname@example.org
Many thanks to all for patience and co-operation.
You actually still don´t need a card to get into the park. All you need is your letter of confirmation that you have applied for a new card. If you don´t have a letter of confirmation i would advise to send an email to Joep.
